SMOKE-CONSUMING- MECHANISM.

Specification of Letters Patent.

Patented Nov. 18, 1913.

Application filed October 14, 1912. Serial No. 725,561.

To all whom; it may concern:

Be it known that I, DELMAR D. KELTNER, citizen of the United States ofAmerica, and resident of Des Moines, Polk county, Iowa, have invented anew and useful Smoke- .Consuming Mechanism, of which the folprovideimproved means for clarifying products of combustion discharged througha draft flue or chimney.

A further object of this invention is to provide improved means forcollecting and precipitating heavy matter carried with the products ofcombustion through a draft flue or chimney.

Afurther object of this invention is to provide improved means forgathering in solution the heavier elements contained in products .ofcombustion carried through a draft flue or chimney.

My invention consists primarily in means for subjecting products ofcombustion through centrifugal action to a mechanical separation of theheavier and lighter elements thereof.

My invention consists further in means for subjecting products ofcombustion to centrifugal action, to combustion, and to a shower bath,to the end of separating the heavier elements from said products,consuming by heat all of the combustible ele- V ments of said products,and taking insolution and precipitating the non-combustible solubleelements.

My invention consists in the construction, arrangement and combinationof elements hereinafter set forth, pointed out in my claims andillustrated by the accompanying drawing, in which Figure 1 is a sideelevation of a mechanism embodying my invention. Fig. 2 is a verticalsection of the'same. Figs. 3, l and 5 are cross-sections on theindicated lines in Fig. 2.

In the construction of the apparatus as shown the numeral 10 designatesa smoke fiue or chimney leading from a furnace, fire box or combustionchamber not shown. A casing 11 is mounted concentric with and extendingabove the upper end of the chimto the chimney. The casing 11 whollysurrounds. and is of materially greater diameter than the chimney l0 anda containing vessel, tank or retort 12 is mounted be neath said casingsurrounding said chimney V and communicates with the casing through aplurality of pipes 13. The tank 12 is provided with a man-hole andclosure 14 of common form in one side and also is provided with adischarge pipe 15 preferably leading from the upper portion thereof. Itis the function of the tank 12 to re ceive substance in solution drainedthrough the pipes 13 from the casing 11. A ball race 16 is mounted inthe lower portion of the casing 11 and is spaced from the wall of saidcasing and the bottom thereof and also is arranged concentric with thechimney 10.-

A bowl 17 is mounted within the casing 11 concentric with the chimney 10and said bowl is formed with a ball race 18 on its lower end parallelwith the ball race 16 and spaced therefrom by a gang of balls 19. Thebowl 17 is open at its lower end and is reticulated or perforated aboveits center. A ball race 20 is mounted in the casing 11 and is spacedfrom the top and walls there of and a ball race 21 is formed on theupper end of'the bowl 17 and is separated from said ball race 20 by agang of balls22. Thus is the bowl 17 mounted for rotation on a verticalaxis within the casing 11. A baffle plate 23 or deflector is mountedtransversely ofand spaced from the wall of the bowl 17 above andextending across the open upper end of the chimney 10. It is thefunction of the baffle plate or deflector to arrest theflow of productsof combustion from the chimney 10. The upper end portion ofthe bowl 17may be entirely closed or it may be provided with an aperture such as'24 at its center, said aperture when em- 'ployed serving to dischargeclarified gas from the bowl.

A draft flue or chimney 25 communicates with and rises from the upperend portion of the casing 11 and the entrance to said flue is spacedfrom the upper end of the bowl 17. The casing 11 also is provided with amanhole and closure 26.

The bowl 17 may be rotated by any desired means but for such purposethere is shown a gear-ring 27 on and surrounding the central portion ofsaid bowl, a spur gear 28 meshing with said ring, a shaft 29.n1ountedfor rotation in the casing 11 and carrying said spur gear, and a motor30 outside the casing and adapted to drive said shaft, said motor beingshown as carried on a bracket 31 fixed to the casing. It is the functionof the rotating bowl to subject the products of combustion 'tocentrifugal action to the end of discharging the heavier elementsthereof, such as carry pigment or colored matter, centriIugally throughthe reticulated portion of the bowl and between said bowl and the wallof the casing. Blasts of hot air, flame or other combustion-producingelements may be discharged within the-casing and within the bowl througha plurality of pipes 32 from a source of supply and serve to inflame andignite the combustible elements of the products of combustion. The tubes32 preferably extend upwardly within the bowl 1? to points near theupper end of the chimney 10 so that they may discharge into the smokeand products of combustion as the latter pass into the bowl.

An annular perforated pipe 33 is mounted in the upper portion ofthecasing 11 and is supplied with liquid such as water or steam through apipe 34. It is the function of the'perforated annular pipe 33 todischarge a shower of liquid on the products of combustion within thecasing 11 to the end oftaking into solution the non-combustible solubleelements thereof and draining them through the pipes 13 into the tank12. The clarified gas remaining after the triple action of centrifugalforce, ignition and solution is discharged across the pipe 33 and ballrace 20 into and through the chimney 25. This is in addition to suchclarified gas as may be discharged centrally and axially from the bowlthrough the hole 2 1.

I do not desire to be understood as limit- 7 ing myself to theconstruction and arrangement of parts herein set forth as the same maybe modified in numerous particulars without departing from thes'pirit ofmy invention.

I claim as my invention 1. A smoke consuming apparatus, comprising areticulated bowl mounted for ro-- tation in the path of travel of andadapted to receive products of combustion, spraying means superposedrelative to said bowl, igniting means arranged contiguous to said bowl,and a receiving tank adapted to take drainage from said bowl.

2. A smoke consuming apparatus, comprising a reticulated bowl mountedfor rotation in the path of travel of and adapted,

to receive products of combustion, a baflie plate transversely of saidbowl, spraying means superposed relative to said bowl, drainage meansbeneath said bowl, and igniting means contiguous to said bowl.

31A smoke consuming apparatus, comprising a reticulated bowl mounted forrotation in the path of travel of and adapted to receive products ofcombustion, a bafiie plate transversely of said bowl, spraying meanssuperposed relative to said bowl, drainage means beneath said bowl,igniting means contiguous to said bowl, and a casing inclosing saidelements. I

4:. In a device of the class described, a smoke stack, a bowl providedwith openings in the upper portion of its side walls and with acomparatively larger opening in its upper end receiving the upper end ofsaid stack and extending above and below said upper end, means forimparting rotary. motion to said bowl, means for injecting fresh airinto smoke passing from said stack into said bowl, a casing receivingand spaced from the side walls of said bowl, and means for sprayingwater between said bowl and said casing. I

5. In a device of the class described, a smoke stack, means forsimultaneously mingling fresh air with and imparting rotary motion tothe smoke emerging from said Witnesses: S. 0. SWEET, W. WV. FINK.
